Choosing to stay single is not something just anyone can do

Regardless of gender,
I believe that staying single is not something just anyone can do.
If we consider human perfection to be 100,
wouldn't marriage be for those who are less than 100 and wish to fill those gaps,
or those who are more than 100 and wish to share their abundance?
I believe those who can maintain exactly 100
are the ones who can live happily as those who choose to remain single.
